Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information handling systems face challenges in accommodating pluggable modules of varying lengths within a chassis, necessitating a solution for adjustable depth adjustment to ensure proper fit and functionality.
Innovation Solution
A midplane assembly within a chassis that includes a connector, locking mechanisms, and pluggable modules with varying lengths, allowing the midplane assembly to translate to different positions based on the module length, engaging or disengaging locking mechanisms to adjust depth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-depth midplane assembly is used in the chassis, then the structure is simple and stable, but it cannot accommodate pluggable modules of varying lengths
Solution Approach 1:
The midplane assembly is designed with movable locking mechanisms that can transition between engaged and disengaged states, allowing the assembly to dynamically adjust its position along the track. This dynamic capability enables the fixed-depth midplane structure to accommodate pluggable modules of varying lengths while maintaining structural simplicity.
Solution Approach 2:
The locking mechanisms are configured to engage at different positions along the track depending on the length of the installed pluggable module. By changing the engagement position parameter of the locking mechanisms, the system adapts to different module depths without requiring a completely different midplane structure.
2Adaptability or versatility
If locking mechanisms are added to enable depth adjustment, then modules of varying lengths can be accommodated, but the device complexity increases
Solution Approach 1:
The locking mechanisms are designed to automatically engage with the track at the appropriate position based on the length of the pluggable module installed. This self-adjusting capability eliminates the need for complex manual adjustment mechanisms or additional control systems, achieving adaptability while minimizing added complexity.
3Adaptability or versatility
If the midplane assembly is made translatable to different positions, then proper fit for various module lengths is achieved, but the stability of the connection may be compromised
Solution Approach 1:
The locking mechanisms provide a dynamic solution by remaining engaged with the track at the selected position, creating a stable fixed connection once positioned. The ability to move to different positions does not compromise stability because the locking mechanisms ensure secure engagement at each position, maintaining reliable electrical and mechanical connections.

AI summary
An apparatus, including: a chassis, including a track; a midplane assembly, including: a connector; and locking mechanisms, wherein the midplane is coupled to the chassis; wherein when a first pluggable module is coupled to the connector of the midplane assembly, first rails of the first pluggable module are engaged with the track of the chassis and the locking mechanisms engage the chassis to place the first pluggable module in a first position with respect to the chassis, wherein when a second pluggable module is coupled to the connector of the midplane assembly, second rails of the second pluggable module are engaged with the track of the chassis and an extension of each of the second rails engages respective locking mechanisms to disengage the respective locking mechanisms from the chassis such that the midplane assembly is translatable with respect to the chassis to a second position differing from the first position.
